Lawyers for John Demjanuk have filed papers attempting to reinstate the former Nazi prison guard's United States citizenship. Demjanjuk was stripped of his citizenship after it was discovered he lied about his Nazi past. In May he was convicted in Germany on 28,000 counts of accessory to murder.

Demjanjuk's case is well-known in Israel where he was released in 1993 following a long and much-publicized trial for being Ivan the Terrible, a notorious Nazi prison guard.

In 2011 German courts ruled that Demjanjuk willingly agreed to serve as a guard at the Sobibor death camp during during the Holocaust. The United States government asked Cleveland, Ohio Judge Dan Polster to reject Demjanjuk's bid to reopen his citizenship case.
